PUMP.
v SPECIFICATION forming partof Letters Patent No. 741,627, dated October 20, 1903.
Original application filed May l 5, 1902, Serial No. 107,426.
To @ZZ whom it may concern:
Be it known that l, GEORGE F. CONNER, a citizen of the United States of America, and a resident of the city of Port Huron, in the county of St. Clair and State of Michigan, have invented new and useful Improvements in Pumps, of which the following is a full, clear, and exact specification.
This invention relates to pumps, and especially to the type referred to in my application, Serial No. 107,426, for feed-water heatvisional application.
The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.
Referring to the drawings, Figure 1 is a view, partly in elevation and partly in section, showing the barrel and piston of a pump embodying the principal features of the invention. Fig. 2 is a view in cross-section-on line 2 2 of Fig. 1.
Referring to the drawings, A represents a ing-box c. and packing-ring c of any preferred design, in-which reciprocates a solid piston B. Said cylinder is normally disposed in a practically horizontal position; but when in use with a portable engine it is frequently inclined at quite a sharp angle. The piston B is cylindrical, but the bore of the pumpbarrel is shaped in cross-section, preferably, as indicated, so as to provide for an air-space above the piston of such a contour, preferably, that its greatest height will be attained at a point Where the discharge-port a2 is situated. Obviously any arrangement may be used which will obtain the result. As shown herein, the vertical diameter of the pumpbore is gradually increasedV in length from either end of the cylinder until the dischargeport is reached. Here the vertical diameter reaches its maximum, and a gland or upward swelling in the cylinder itself carries the wall at this point still farther away from the piston. The exhaust-port is' situated near the this construction any air which may enter the pump-cylinder rises into this space above the piston and readily escapes through the dis- Divided and this application filed January 7, 1903. Serial (No model.) A
ton being always the same, as itis always en-` tirely immersed at the end of its' outstroke. As a result the water is forced out of the pump at a constant head and the tilting of the cylinder due to the passing of the engine over a-rough or hilly road does not affect the pump working, as the piston displacement is constant even under varying positions of the 0 pump itself.
It will be understood, of course, that any arrangement of ducts or passages may be used which would collect the air at the upper part ofthe cylinder and lead it' to the exhaustport of the pump.
The actuating parts of the piston may be of any desired design.
The arrangement herein shown, while preferable, may be varied without departing from the spirit of the invention, and I do not limit myself to any particular form of construction except as set forth in the claims.
I claim as my invention- 1. A pump havinga cylinder provided with an air-gathering recess opening into said cylinder, said' recess extending from end to end of the cylinder, and an exhaust-port leading fromsaid recess.
2. A pump having an approximately horizontal cylinder provided with a channel extending from end to end of the cylinder along its inner face above the piston, and a single exhaust-port leading from said channel to without the cylinder.
3. A pump having an approximately horizontal cylinder, a single exhaust-port leading therefrom and an air-gathering recess extending along the inner face of said cylinder above the travel of the piston, whose" height increases from either end of the cylinder to the exhaust-port into which it discharges.
4. A pump having an approximately horizontal cylinder, a piston reciprocable therein, a single exhaust-port leading therefrom, and
IOO
a recess in the cylinder-face extending from end to end of the cylinder discharging into said exhaust-port.
5. A pump having an approximately horizontal cylinder, a piston reciprocalole therein, :i single exhaust-port leading therefrom, the vertical diameter of said cylinder increasing from either end of the cylinder until the eX- hztust-port is reached, said enlarged portion 1 forming an air-gatheringreeess above the line Io of travel of the piston.
In testimony whereof I have signed my name in the presence of two subscribing Witnesses.
GEORGE F. CONNER. Witnesses:
D. E. PURDY, C. R. STICKNEY.
